Festival decoration lamp string with multiple parallel wires and preparation method of festival decoration lamp string

Abstract

The invention relates to a festival decoration lamp string with multiple parallel wires and a preparation method of the festival decoration lamp string. The festival decoration lamp string comprises alamp string body which is internally provided with the anode wires and the cathode wires, wherein the anode wires and the cathode wires are arranged in parallel in the axial direction; a plurality ofanode solder joints and first breakpoints are arrayed on the anode wires, and a plurality of cathode solder joints corresponding to the anode solder joints, and second breakpoints are arrayed on thecathode wires; a lamp soldering area is formed opposite to the anode solder joints and the cathode solder joints; and LED lamp beads are flatly or laterally attached into the lamp soldering area, thefirst breakpoints and the second breakpoints are arranged on the anode wires and the cathode wires in a staggered mode correspondingly, and meanwhile the first breakpoints and the second breakpoints are vertically staggered, so that the LED lamp beads between the anode wires and the cathode wires are in series-parallel connection. The problem that many LED lamps need to be connected into a traditional lamp string in series in a high-voltage occasion is solved, the current of all sets of LED lamp beads which are connected in series can be very small through the high voltage, the consumed poweris reduced, the constant current is conducted through a series-parallel connection mode, consistency is good, and the cost is lowered greatly.

Description

technical field [0001] The invention relates to the field of lamps, in particular to a festival decorative lamp string with multiple parallel wires and a preparation method thereof. Background technique [0002] Now that people's living standards are gradually improving, light strings are hung up for decoration during holidays and even daily life, which greatly increases the demand for lighting. At present, the festival light string still adopts the traditional structure, such as the festival light string proposed by the patent number CN201520607108. The process is all done manually, the labor cost is high, the labor intensity is high, the production difficulty is increased, the production efficiency is reduced, and finally the production efficiency of the entire light string is affected. [0003] In order to meet the market demand, the production of its light strings is getting faster and faster. The applicant proposed the patent number CN201620043393.9 enamelled copper wi...

At present, the festival light string still adopts the traditional structure, such as the festival light string proposed by the patent number CN201520607108. The process is all done manually, the labor cost is high, the labor intensity is high, the production difficulty is increased, the production efficiency is reduced, and finally the production efficiency of the entire light string is affected.

[0003] In order to meet the market demand, the production of its light strings is getting faster and faster. The applicant proposed the patent number CN201620043393.9 enamelled copper wire LED light string and the patent number CN201620043391.X flexible wire LED light string. In the above light string In the driving circuit of LED, many low-voltage LED constant current driving technologies are used. If it is to be applied to the occasion of 220V AC power supply, it is necessary to adopt the scheme of connecting multiple LED lamps in series, such as Figure 4 , For example, when multiple LED lamps are connected in series, due to the instability of the current, the dissipation power of the LED lamps will increase, and the situation of burning out the LED lamps will often occur, and at the same time, the cost will increase accordingly, or the AC / DC power supply will be increased. Part, providing a lower DC voltage, this solution will greatly increase the cost
